To @ZJ whom t 11mg/ concern:

Be it known that I, JOHN P. NESSLE, a citizen of the United States,residing at Newark, 1n the county ot Essex and State of New Jersey, haveinvented certain new and useful Improvem ents in Railroad-Rails, otwhich the tollowing is so full, clear, and exact a description as willenable others skilled in the art to which my invention appertains tomake and use the same, reference being had to the accompanyingdrawings,iu whichn Figure l is a perspective view of my improved rail,showing it in position on the stringer. Fig. 2 is a cross-section of thesame. Fig. is a perspective View of a modification. Fig. 4 is across-section of the latter.

The object of my invention is to construct a railroad-rail by the use ofwhich a continuous unbroken compound track will be secured, causing thecar to run smoothly along the road-bed with the greatest ease and theleast noise and with the least liability of injury to the car or thetrack.

Another object of my invention is to provide a track for railways ortramways which may be readily removed and replaced when the sectionsbecome worn to such an extent as to render. their removal desirable.

Another object of my invention is to provide a railroad-rail by the useof which the spreading of the tracks away from each other will beavoided and the pressure and strain on the stringers will be direct andcentral.

Another object of my invention is to produce a rail which when laid willbe practically solid and at the same time possess sutiicient elasticityto enable it to adapt itself to the varying degrees of heat and cold.

Another object of my invention is to provide a track by the use ot whichthe railroad company will secure to its passengers and employs thegreatest degree of comfort ou account of the absence of rattling,rumbling, and jars incident to railroading over ordinary tracks.

My invention consists in the novel construction, combination, andarrangement of parts, as will be hereinafter fullydescribed, andparticularly pointed out in the claims at the end of the specification.

In the accompanying drawings, A designates the upper section of therailroad-rail7 which is of equal length with the lower section B. Thesection A has a center-bearing rail-head C, which is grooved or hollow,as shown at a. This grooving of the top section A has many advantages,among which may be mentioned the lightening` of the rail and theconsequent reduction of its cost; second, the recess a in the rail formsan admirable means of securing the section A against lateraldisplacement by dropping the section A over the section B in such amanner that the projecting tongue b of the section 3 will lit withinlthe groove a in section A, as shown in Figs. l and 2; third, thesection A, being only about half ot the weight which is required for thecompleted rail, is much more easily handled and may be taken up and putdown quicker and more easily than could be done if the rail proper werenot made in sections. Again, the upper sections of the rail are the onlysections which need be of finer grades of iron or steel, and the lowersection may be made of a cheaper grade of iron, at the same timeproviding a track which will have all the advantages of solid steel andcontinuous rails, with the additional advantage of the elasticity whichis the result of the combination of the sections described, the samebeing overlapped with broken joints, as shown. It will be readilyunderstood that the sections will be readily reversible on account oftheir being all alike and of unitormlength, so that when one side of therail-head becomes worn the rail maybe taken up and turned half aroundand replaced in the same position on the track.

The sections B (shown in Figs. l and 2) consist of elongated flat plateshaving downwardly-projecting iianges c c, which are adapted to embracethe Stringer D over its upper edges. On the central portion of the plateB, l form a projecting head or tongue b. The sections are secured to theStringer D by bolts which extend through bolt-holes in the sections,said holes being elongated in the usual way to allow for crawling andthe natural expansion and contraction caused bythe varying temperature.The lower sections of the track are intended to be secured to theStringer and allowed to remain there permanently, while defective andworn-out sections ofthe top of the track may be removed and replaced atwill without rcmovin g the lower IOO sections. In the torni shown inFigs and il, the lower section is made with a projecting tongue or ribwhich is adapted to enter a corresponding groove in the rail, which inthis instance is to one side ot the center ot the line ofthe rail. Itwill be understood that the head of the rail will protect the rib ortongue against any injury which it would receive if exposed to contactwith passing' vehicle or car wheels.

From the foregoing` it will be readily understood that the cost ofkeeping such a track in repair is reduced to a minimum, both on accountot a saving in the cost. ot material and the facility with which theupper sections ot` the track may be removed and replaced. The saving inthe absence of the rattling and j arrin g oi the rollin g-stock is alsoa matter of grave importance in this connection, and it is always agreat desideratum in the running of a railroad.

llaving described the objects, uses, and advantages of my device, what Ibelieve to be new, and what I desire to secure by Letters Patent, andtherefore claim, is

1. A compound railfor railways, consisting oi' a lower section providedwith a projecting rib or head and having projecting flanges extendingfrom the opposite sides adapted to embrace t-he Stringer, combined withan upper section having a head provided with a longitudinal grooveadapted to receive the rib or head of the lower section, the sameadapted to be secured together with broken joints to form a continuouscompound rail, substantially as and for the purposes specified. Acompound rail for railways, consisting of a lower section provided witha projecting rib or head and having projecting flanges extending fromthe opposite side adapted to ein` brace the stringer, combined with anupper section having a central head provided with a longitudinal centralgroove adapted to rcceive the rib or head ot' thelower section, the sameadapted to be secured together with broken joints to form acontinuouscompound rail, substantially as and Vfor the purposes specified.

In testimony whereof I ailix my signature in the presence ot twowitnesses.
